The correct answer for the question is option 2: 2 and 4 only.

Let`s analyze each option:

1. The Trade Union movements in post-colonial India: While trade union movements in post-colonial India address sociological issues related to workers` rights and labor conditions, they do not specifically address ecological issues.

2. Narmada Bachao Andolan: This movement specifically addresses both sociological and ecological issues. It is a social movement protesting against the construction of large dams on the Narmada River in India, which has significant environmental and social impacts.

3. Jai Prakash Narain`s movement for total revolution: This movement, led by Jai Prakash Narain, focused on political reform and social justice but did not specifically address ecological issues.

4. Chilka Bachao Andolan: This movement, also known as the Save Chilka Movement, was a grassroots movement in Odisha, India aimed at protecting the Chilika Lake ecosystem and the livelihoods of the local fisherfolk. It addresses both sociological and ecological issues.

Therefore, the Narmada Bachao Andolan and Chilka Bachao Andolan are the movements that address both sociological and ecological issues.
